Boat Docking and Cleaning Device

ABSTRACT

A docking and cleaning device comprising a frame having scrubbers affixed thereto for cleaning a boat hull at a horizontal section, such as the waterline. The frame comprises a movable elongated member so that when the frame is in an “open” position, the elongated members provide an opening through which a boat may pass, entering into a docking area formed by the frame. The elongated member is moved so that the frame is in a “closed” position where the frame substantially conforms to the shape of the boat hull. Wave motion acting on the boat and the frame allow the scrubbers to frictionally contact and clean the boat hull at the waterline.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a boat docking and cleaning device. Thedevice holds the boat in position a desired distance away from a dockwhile cleaning a horizontal cross-section, such as at the waterlinesection, of the boat hull.

2. Description of Related Art

An ongoing problem for experienced and novice boaters alike is thedocking of their boats without contacting nearby stationary structures,such as a dock. Such contact may often cause scuffs or damage to theboat hull. When docking, most boaters require assistance from a docksideassistant or passenger to handle ropes or to push off the dock. Thisassistance is especially needed on the approach to a dock where currentsand wave action may affect a projected course. Commonly, where waves andcurrents are an issue, docks are equipped with fenders to absorb anycontact by an approaching boat. Alternatively, once the boat is docked,various fenders may be placed either along the dock or on the side ofthe boat hull to prevent physical damage that may result from the boathull contacting with the dock due to wave action. Various fender devicesare discussed, for example, in U.S. Pat. Nos. 5,018,471 to Stevens and5,732,645 to Lemke. A drawback of these fenders is that the impact theyare designed to absorb is not distributed over a large area. Thus, thefenders may damage the boat hull or the dock in the position where theyare located.

Boat owners are also routinely confronted with maintenance tasksassociated with keeping a boat docked in the water for periods of time.The attachment of organic material and the formation of slime on theboat hull at the waterline is unsightly and may damage the boat hullover time. Thus, cleaning the boat hull is a task that is generallyperformed at intervals by the boat owner using mechanical brush deviceswhile standing on the deck of the boat or from dockside. U.S. Pat. No.4,648,344 to Burgers et al. discloses the use of a brush to clean theboat hull while standing on a dock. Alternatively, the boat may beremoved from the water and dry-docked to access the boat hull forcleaning.

Other conventional boat hull cleaning devices provide scrubbing actionlaterally across the bottom of the boat hull, port to starboard (left toright). These devices are inconvenient to use because they usuallyrequire moving the cleaning device along the boat hull to clean theentire hull. Alternatively, if the cleaning device is mounted in a fixedposition, the boat itself must be moved past the cleaning device toclean the entire hull. In this regard, U.S. Pat. No. 4,843,995 toBingham discloses a boat hull cleaning device mounted in a fixedposition adjacent to a water passageway. A line stretched across thepassageway cleans the boat hull by passing the boat over the line, whichforces a scrubber section of the line against the boat hull. Maloney etal., U.S. Pat. No. 5,222,452 (“the Maloney '452 patent) discloses a boathull cleaning apparatus mounted to a dock. The apparatus comprises a rowof motorized rotary brushes extending into the body of water. A boat ismoved past the row of brushes to clean the boat hull.

Other hull cleaning devices provide scrubbing action longitudinallyalong the bottom of the boat hull from bow (front) to stern (back),instead of laterally across the bottom of the boat hull from port tostarboard. For example, Rogers, U.S. Pat. No. 4,401,048 discloses adevice that scrubs a longitudinal section of a boat hull. The boatremains stationary in the water, and the device moves along the boathull from bow to stern to clean the underwater portion of the boat hull.The device cleans a section of the boat hull in the particular locationwhere the device is positioned. The device must be repositioned to cleanthe remaining sections of the boat hull.

Despite the various conventional docking and hull cleaning systems knownin the art, there remains a need for a docking system that maintains aboat in position away from the dock and cleans the boat hull at thewaterline without taking the boat out of the water.

BRIEF SUMMARY OF THE INVENTION

The present invention is directed to a docking device for guiding a boatinto a docking area and holding the boat in position while cleaning theboat hull periphery at a horizontal cross-section of the boat,preferably at the waterline. The present invention is also directed to amethod for the simultaneous docking and cleaning of a boat using such adevice.

In one aspect, the boat docking and cleaning device of the presentinvention comprises a frame shaped to conform to a shape of asubstantial portion of a horizontal cross-section of a boat hull. Theframe is such that is it conforms to at least 50%, 60%, 70%, 80%, 90%,or 100% of the horizontal cross-section of the boat hull, preferably atthe water line. In the latter case (100%), the frame completelysurrounds the boat hull a horizontal cross section (e.g., at the waterline). In other aspects, the frame surrounds about 50 to 100%, about 50to 90%, about 50 to 80%, about 50 to 70%, about 60 to 100%, about 60 to90%, about 60 to 80%, about 70 to 100%, about 70 to 90%, about 70 to 80%of the boat hull.

In one aspect, the frame preferably comprises a first elongated member,a second elongated member, and an optional base section. The firstelongated member and the second elongated member each have a first endand a second end. The first end of the first elongated member and thefirst end of the second elongated member are movably, preferablypivotably, connected to each other. Alternatively, at least one of thefirst elongated member or second elongated member is movably, preferablypivotably, connected to the optional base section. The second end of thefirst elongated member and the second end of the second elongated memberare movably connected to each other such at least one of the second endsare adapted to move toward and away from each other in an “open” and“closed” position. A scrubber is affixed to the frame for cleaning theboat hull. Preferably, the scrubber frictionally engages and cleans atleast 50% of the boat hull at the waterline. Thus, in one aspect, thescrubber frictionally engages and cleans at least 50%, 60%, 70%, 80%,90%, or 100% (or some range therebetween) of the horizontalcross-section of the boat hull, preferably at the water line. In otheraspects, the scrubber frictionally engages and cleans about 50 to 100%,about 50 to 90%, about 50 to 80%, about 50 to 70%, about 60 to 100%,about 60 to 90%, about 60 to 80%, about 70 to 100%, about 70 to 90%,about 70 to 80% of the boat hull.

In another aspect, the first elongated member and/or the secondelongated member of the frame comprise a plurality of frame sections.Further, in another aspect, the scrubber comprises a plurality ofscrubber segments mounted on the frame or frame sections. The scrubbersegments may form a continuous scrubber such that there are no gapsbetween adjacent scrubber segments, or may be non-continuous. Thescrubber segments are preferably adjustable so that the angle of thescrubber relative to the waterline (i.e., relative to horizontal) may beadjusted depending on the shape of the boat hull or the depth at whichthe device floats in the water. The angle is typically about 30, 40, 45,50, 55, 60, 65, 70, 75, 85 degrees relative to horizontal or some rangetherebetween.

In still another aspect, the frame comprises a first and secondelongated member movably connected, preferably pivotably, to a basesection. The base section may be adapted to conform to the shape of thebow of the boat or the shape of the stern of the boat.

In yet another aspect, the docking and cleaning device is comprised ofmaterials so that the device floats at or just below the waterline of abody of water. Typically, the device floats no more than 0, 1, 2, 3, 4,or 5 feet below the waterline (or some range therebetween).

The present invention is also directed to a boat docking and cleaningsystem comprising the boat docking and cleaning device as describedherein, and further comprising least one mooring line. The mooring linesare used to tether the device to the dock and/or pilings.

In another aspect, the present invention is directed to a docking andhull cleaning device comprising a frame having a first elongated memberand a second elongated member. At least one of the elongated members ismovable (preferably pivotable) between a closed position and an openposition. In the closed position, the frame defines an interior boatdocking area. The frame is complementary in shape to a boat hull at ahorizontal cross-section thereof when the elongated members are moved tothe “closed” position. The frame is adapted to form an opening fordocking or undocking the boat when the elongated members are moved tothe “open” position. A scrubber is affixed along at least a portion ofthe interior of one frame. Preferably, the scrubber frictionally engagesand cleans at least 50% of a boat hull at the waterline.

In another aspect, the present invention is directed to a method fordocking a boat and cleaning the hull of a boat. The device as describedherein is floated on a body of water. The frame of the device, which isshaped to conform to the shape of a horizontal cross-section of the boathull (preferably at the waterline or just below the waterline), definesan interior docking area for the boat and has a scrubber mountedthereon. The boat is placed in the interior boat docking area to dockthe boat and permit the scrubber to frictionally engage the boat hull toclean the boat. Typically, the frame of the device is moored to the dockand/or piling(s) using at least one mooring line.

In one aspect, the method for docking and cleaning the boat includesproviding a device in which the frame comprises a first elongated memberand second elongated member pivotably connected to an optional basesection or to each other. In such a case, the boat is placed in theinterior docking area by pivoting the first and/or second elongatedmembers to form an opening in the frame.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

The present invention is directed to a boat docking and cleaning devicefor guiding a boat into a docking area and holding the boat in positionwhile cleaning a substantial portion of a horizontal cross-section ofthe boat hull periphery, preferably at the waterline. The presentinvention is also directed to a method for docking a boat and cleaning aboat hull using the devices disclosed herein.

The docking and cleaning device generally comprises a frame and one ormore scrubbers attached to the frame. In a preferred embodiment, theframe comprises a first elongated member, a second elongated member, andan optional base section. One or more of the first and second elongatedmembers are movable in an “open” position and a “closed” position. Inthe “open” position, the frame and scrubbers provide a resilient bumperto aid a boater in maneuvering the boat into the docking area. Once inthe docking area, the elongated members of the frame are moved to a“closed” position, wherein the frame preferably completely surrounds theboat hull at the waterline including the bow, sides, and stern portionsof the boat hull. In this position, the device is adapted to allow theboat to move up and down with the motion of the water and yet avoidundesirable contact with the dock associated with dock mooring. Further,the scrubbers positioned on the frame function as both a resilientcushion against the boat hull while docking and as a scrubber while theboat is docked to clean the boat hull at the waterline region. Thescrubbers frictionally contact the boat hull at the waterline and cleanthe boat hull as the frame and hull move in response to the motion ofthe surrounding water.

As used herein, the term “boat” includes any type of watercraft designedto float or plane on water, including but not limited to motorboats,sail boats, and jet skis.

As used herein, the terms “float,” “floating,” and “floatable” mean thepositional status of being or the ability to be afloat either at, on, orbelow the surface of a body of water (typically not more than 5 feetbelow the surface of the body of water) and not sink to the bottom ofthe body of water.

While several exemplary embodiments of the present invention arediscussed below, those skilled in the art will readily appreciate thatvarious modifications may be made to these embodiments, and theinvention is not limited to the configurations described therein. Forexample, the frame of the boat docking and cleaning device may beconstructed of a number of different members and materials, providedthat the frame surrounds a majority of the boat hull at a horizontalcross section. In that regard, many of the exemplary embodimentsdiscussed below are preferred embodiments in which the frame (andscrubbers) are designed to contact boat hull at the entire horizontalcross-section. That is, the frame extends around the entire (100%)periphery of the boat hull at a horizontal cross section (e.g., at thewaterline). However, it is within the scope of the present inventionthat the frame (and/or scrubbers) could extend around 50%, 60%, 70%,80%, or 90% of the boat hull, and still be able to clean a substantialportion of the boat hull while docking the boat as generally shown inthe seventh embodiment. In such a case, it is anticipated that the frameends (e.g., the ends of the two elongated members) could be connectedtogether using a rope, chain, or other connection device. In such acase, the boat would still be docked within an interior docking areadefined by the docking device (the frame connected together by therope).

First Exemplary Embodiment

Referring to FIGS. 1, 2, and 3, a combination docking and cleaningdevice in accordance with a first exemplary embodiment of the presentinvention is designated generally by the number 10. The device 10comprises a frame 12 having a base section 14 attached to two elongatedmembers 20A, 20B. The frame 12 is shaped so that the bow of a boat 28 isdocked first. Once the boat is docked, the shape of frame 12 generallyconforms to the shape of the boat hull at the waterline cross-section.

FIG. 1 illustrates the docking and cleaning device 10 in an “open”position with a boat 28 positioned therein. FIG. 2 illustrates thedocking and cleaning device in a “closed” position with the same boat 28positioned therein. As shown in both FIGS. 1 and 2, the base section 14is generally shaped to correspond to the bow of the boat 28. Thus, thebase section 14 is generally V-shaped and comprises first and secondmembers 14A, 14B which converge and join at apex 16 at one end andextend and bow outwardly from apex 16 to ends 18A, 18B.

The docking frame 12 further includes two elongated members 20A, 20Bhaving first ends 22A, 22B and second ends 24A, 24B. The elongatedmembers 20A, 20B are generally adapted to engage the boat stern. Thefirst ends 22A, 22B are pivotably attached to ends 18A, 18B of the basesection 14 respectively at movable joints 26A, 26B. The second ends 24A,24B are adapted to move or swing toward and away from each other aboutmovable joints 26A, 26B. This permits docking of the boat 28 asgenerally illustrated in FIG. 1. As shown in FIG. 2, the second ends24A, 24B are removably connected to each other to form the encloseddocking area. Typical connection devices used to removably connectsecond ends 24A, 24B of the elongated members include, but are notlimited to latches, clasps, hooks and eyes, buckles, ties, rope, locks,and the like.

In this embodiment, the elongated members 20A, 20B generally curvetoward each other so that their shapes correspond to the shape of thestern of the boat 28 when the frame is in a “closed” position. As shownin FIGS. 1 and 2, elongated members 20A, 20B are generally L-shaped.

FIG. 3 illustrates the cross-section of the device 10 floating on thewater surface. The cross-section can be taken along any part of theframe of the device. The frame 12 has a cross-section which is generallyrectangular in shape, but it will be appreciated to those skilled in theart that other shapes, such as circular, elliptical, and the like arewithin the scope of the present invention. The frame 12 is preferablymade of a material which is buoyant, rot-proof, rust-proof, and waterresistant. Exemplary materials include wood, plastic, fiberglass, ormetal. Alternatively, if the density of a selected material for theframe 12 does not allow it to float on the surface of the water, theframe 12 may optionally be configured with flotation devices such asbuoys (not shown) attached to the frame 12 to allow the frame 12 tofloat at the water's surface.

As shown in FIG. 3, a scrubber 50 comprising a plurality of brushes 52is connected to the interior of the frame 12. The scrubber 50 preferablyextends along the entire interior periphery of the frame 12 such thatthe brushes 52 frictionally engage the entire horizontal cross-sectionof the boat hull (i.e., the bow, stern, and sides) at the waterline asgenerally shown in FIG. 2 when the boat is in a “closed” position.Preferably, the scrubber 50 extends along at least 50%, 60%, 70%, 80%,90%, or most preferably at least 95% of the periphery of the frame 12such that the brushes 52 engage a corresponding portion of thehorizontal cross-section of the boat hull at the waterline. The brushescan have a variety of thicknesses and may have brush densities optimizedfor cleaning the device but that are easily cleaned by washing.

As shown in FIG. 3, the scrubber is adapted to generally contact theboat hull at the waterline. The brushes 52 are preferably comprised ofanti-abrasive bristles made of synthetic material, such as nylon,suitable for the marine environment. Optionally, the scrubber 50 maycomprise carpet pads or elastomeric pads, and may be mechanicallyactuated and controlled as generally shown in the Maloney '452 patent,which is incorporated by reference. Preferably, the scrubbers areresilient and provide impact absorption.

In FIG. 3, the scrubber 50 is attached to the frame 12 using one or moresupport brackets. The angled C-shaped bracket 49 is affixed to the topand bottom of frame 12 using one or more fasteners 48 (e.g. nails,screws, bolts, adhesive, Velcro and the like). One or more elongatedbrackets 44 are attached to the scrubber 50 at one end and are attachedto the C-shaped bracket 49 using fasteners 48 at the other end. Thebracket 44 preferably includes an elongated aperture or slot 46 toadjustably engage the fasteners 48 such that the position and/or angleof the scrubber 50 is adjustable. Alternatively, the frame 12 may beshaped so that it is tightly held within bracket 49 without the need forfasteners.

Further, it will be appreciated that various other fastening means forattaching the scrubber 50 to the frame 12 and attaching elongatedbracket 44 to C-shaped bracket 49 are well known, such as hook and loopfasteners, clips, u-bolts, and rivets, are within the scope of thepresent invention.

The scrubber 50 is preferably angled so that the brushes 52 frictionallyengage the boat hull at the waterline, where the majority of the slimeand other aquatic material is most likely to accumulate on the boathull. In FIG. 3, the angle of the scrubber is such that the brushes 52engage the boat hull at the radius of curvature defined by the boat hullat the waterline. The angle θ of the scrubber is preferably 30 to 85degrees relative to horizontal, and is typically about 60 to 80 degreesrelative to horizontal (i.e., relative to the waterline).

Looking at FIGS. 1 and 2, the frame 12 is held in position in relationto the dock 54 by a mooring system 56. The mooring system 56 comprisesone or more pilings 58 and one or more mooring lines 60. The mooringsystem 56 further includes various cleats, shackles, pulleys, and othertying-off devices as is known to those skilled in the art (not shown).Exemplary mooring lines 60 include ropes, cable, chains, and the like.

FIGS. 1 and 2 show the top ends of the pilings 58 which are part ofmooring system 56. Typically, the bottom end of pilings 58 are securedto the bottom of the sea or water bed or the submerged part of anadjacent marine structure. The first end of each mooring line 60 isattached generally to the top end of pilings 58 and the second end ofeach mooring line 60 is attached to the frame 12 at attachment point 62.The attachment point 62 is typically a cleat or ring (not shown).Optionally, the first ends of the mooring lines 60 may be attached tothe dock 54 instead of the pilings 58.

With the structure of the boat docking and cleaning device set forthabove, the operation of the device will now be described. Looking toFIG. 1, the mooring lines 60 of mooring system 56 are adapted to allowthe frame 12 to be positioned in a desired location relative to the dock54. Typically, tension in the mooring lines 60 is set to keep the frame12 from unwanted contact with the dock 54 while still allowing for thelimited movement of the device 10 caused by the tide and the wave actionof the water.

As shown in FIG. 1, for a docking operation, the frame 12 is firstplaced in an “open” position by the user. In the “open” position, thebase section 14 and the elongated members 20A, 20B form a generallyV-shape docking area 30. The second ends 24A, 24B of the elongatedmembers 20A, 20B form an opening or entrance to the interior dockingarea 30 through which a boat 28 may pass. As the bow of a boat 28approaches and contacts device 10, the scrubbers 50 mounted to theelongated members 20A, 20B resiliently urge and guide the boat 28 intothe docking area 30. As the boat 28 advances, the scrubbers 50 continueto urge and align the boat 28 into the docking area 30 until the bowcontacts apex 16. Once the bow of the boat 28 contacts apex 16, theelongated members 20A, 20B are moved or swung toward each other untilthe second ends 24A, 24B of the elongated members 20A, 20B are connectedtogether. When the elongated members 20A, 20B, are connected together(e.g., using latches 32A, 32B), the device is in the “closed” positionas generally shown in FIG. 2.

In the “closed” position, the frame 12 forms the enclosed docking area30, holding the boat 28 in a desired position. The boat hull iscontinuously in contact with scrubber 50 on the frame 12 of the device10. The motion of the water, including waves and tidal action, providesmovement of the docking and cleaning device 10 and the boat 28 inrelation to each other. This movement translates into frictional actionof the scrubber 50 against the boat hull. The frictional action ofscrubber 50 against the boat hull provides a scrubbing action tocontinuously clean the periphery of the boat hull at thewaterline—including the sides, bow, and stern—all while the boat is inthe water.

When undocking the boat 28 from docking area 30, the elongated members20A, 20B are moved or swung apart, forming an opening between the secondends 24A, 24B of the elongated members 20A, 20B. The boat 28 then exitsfrom docking area 30 by moving astern between the opening formed by thesecond ends 24A, 24B. The scrubbers 50 on the elongated members 20A, 20Bhelp urge and guide the boat 28 out of the docking area 30 until theboat 28 is clear of the device 10.

In one aspect, the elongated members 20A, 20B are manually moved orpositioned in the “open” and “closed” position. It will be appreciatedto one skilled in the art that latches 32A, 32B and/or elongated members20A, 20B can be equipped with motors or other actuating devices known tothose skilled in the art so that the device is mechanically driven.Further, the motors may be adapted with receivers to respond to remotecontrol command signals to move the elongated members 20A, 20B.

Second Exemplary Embodiment

Referring to FIGS. 4-5, a combination docking and cleaning device inaccordance with a second exemplary embodiment of the present inventionis designated generally by the number 110. The device 110 of the secondexemplary embodiment is different from the device 10 of the firstexemplary embodiment in three principal ways. First, the device 10 ofthe first exemplary embodiment is designed as “bow-first” when docking,while the device 110 of the second exemplary embodiment is designed as“stern-first” when docking. Second, the frame 112 of the device in thesecond embodiment is equipped with ballast tank to alter the depth ofthe frame device 110. Third, the device 110 of the second exemplaryembodiment is comprised of a plurality of scrubber segments instead of acontinuous single scrubber along the frame.

As shown in FIGS. 4-5, the device 110 of the second exemplary embodimentcomprises a frame 112 having a base section 114 attached to twoelongated members 120A, 120B. The frame 112 is shaped so that the sternof the boat 128 is docked first. Once the boat 128 is docked, the shapeof the frame 112 generally conforms to the shape of the boat hull at thewaterline cross-section.

FIG. 4 illustrates the docking and cleaning device 110 in an “open”position with a boat 128 positioned therein. FIG. 5 illustrates thedocking and cleaning device in a “closed” position with the same boat128 positioned therein. As shown in both FIGS. 4 and 5, the base section114 is generally shaped to correspond to the stern of the boat 128.Thus, the base section 114 is generally C-shaped and comprises ends118A, 118B.

As will be apparent, the overall shape of the frame 112 in the secondexemplary embodiment is substantially identical to the frame 12described above with respect to the first exemplary embodiment when inthe “closed” position. As with the first embodiment, the docking frame112 of the second embodiment includes two elongated members 120A, 120Bhaving first ends 122A, 122B and second ends 124A, 124B. The elongatedmembers 120A, 120B are generally adapted to engage the boat bow. Thefirst ends 122A, 122B are pivotably attached to ends 118A, 118B of thebase section 114 respectively at movable joints 126A, 126B. The secondends 124A, 124B are adapted to move or swing toward and away from eachother about movable joints 126A, 126B. This permits docking of the boat128 as generally illustrated in FIG. 4. As shown in FIG. 5, the secondends 124A, 124B are removably connected to each other to form theenclosed docking area. Typical connection devices used to removablyconnect the second ends 124A, 124B of the elongated members include, butare not limited to latches, clasps, hooks and eyes, buckles, ties, rope,locks, and the like.

In this embodiment, the elongated members 120A, 120B generally curvetoward each other so that their shapes correspond to the shape of thebow of the boat 128 when the frame is in a “closed” position. As shownin FIGS. 4 and 5, elongated members 120A, 120B are generally C-shaped.

As shown in FIG. 5A, to float or position the frame 112 at variousdepths in the water, the frame 112 is configured with a hollow core 134similar to a ballast tank that is well known in the art. The hollow core134 is adapted to be filled with water or emptied through tube opening136 to adjust the buoyancy of the frame 112. The tube opening 136 isconfigured with a cap 138 for sealing the contents of the core 134. Whenthe hollow core 134 contains increasing amounts of water or other fillermaterials that correspondingly increases the overall density of theframe. In such a case, the frame 112 floats at a lower level in thewater. Similarly, removing water from the core 134 will raise the levelat which the frame 112 floats in the water.

FIG. 5A also shows that the scrubber 150 is adapted to generally contactthe boat hull at the waterline or just below the waterline. In a mannersimilar to FIG. 3, the scrubber 150 is attached to frame 112 using oneor more support brackets. Again, in this embodiment, the angled C-shapedbracket 149 is affixed to the top and bottom of frame 112 using one ormore fasteners 148. One or more elongated brackets 144 are attached tothe scrubber 150 at one end and are attached to the C-shaped bracket 149using fasteners 148 at the other end. The bracket 144 includes anelongated aperture or slot 146 to adjustably engage the fasteners 148such that the position and/or angle of the scrubber 150 is adjustable.

In the second exemplary embodiment, the angle of the scrubber issomewhat lower than that of the first exemplary embodiment of the deviceillustrated in FIG. 3. The angle of the scrubber is preferably 30 to 85degrees relative to horizontal, and is typically about 60 to 80 degreesrelative to horizontal (i.e., relative to the waterline). Further, whilethe scrubber 50 in the first exemplary embodiment extends along theentire interior periphery of the frame 112 as one continuous scrubberunit, FIG. 5B illustrates a scrubber 150 comprising a plurality ofadjacently positioned scrubber segments 150A-150E to form asubstantially continuous scrubber along frame 112. Each of the scrubbersegments 150A-150E is held in place by the brackets illustrated in FIG.5A, and thus may be independently adjustable to the desired anglerelative to the waterline.

Looking at FIGS. 4-5, frame 112 is typically held in position inrelation to dock 154 by mooring system 156. The mooring system 156 issimilar to that in the first embodiment. One or more mooring lines 160connect the boat docking and cleaning device 110 to the dock 154 and/orpilings 158 at various attachment points 162.

The operation of the boat docking and cleaning device is similar to thefirst exemplary embodiment. Looking to FIG. 4, the mooring lines 160 ofmooring system 156 are adapted to allow the frame 112 to be positionedin a desired location relative to the dock 154. Typically, tension inthe mooring lines 160 is set to keep the frame 112 from unwanted contactwith the dock 154 while still allowing for the limited movement of theframe 112 caused by the tide and the wave action of the water.

As shown in FIG. 4, for a docking operation, the frame 112 is in an“open” position. In the “open” position, the base section 114 and theelongated members 120A, 120B form a generally U-shape docking area 130.The second ends 124A, 124B of the elongated members 120A, 120B providean opening or entrance to docking area 130 through which a boat 128 maypass. As the stern of a boat 128 approaches and contacts device 110, thescrubbers 150 mounted to the elongated members 120A, 120B resilientlyurge and guide the boat 128 into the docking area 130. As the boat 128advances, the scrubbers 150 continue to urge and align the boat 128 intothe docking area 130 until the stern contacts the base section 114. Oncethe stern of the boat 128 contacts the base section 114, the elongatedmembers 120A, 120B are moved or swung toward each other until the secondends 124A, 124B of the elongated members 120A, 12B are connectedtogether. When the second ends 124A, 124B are connected together (e.g.by a latch 132A, 132B on each end), the device 110 is in the “closed”position as generally shown in FIG. 5.

As shown in FIG. 5, in the “closed” position, the frame 112 forms theenclosed docking area 130, holding the boat 128 in a desired position.The boat hull is continuously in contact with the scrubber 150 on theframe 112 of the device 110. The motion of the water, including wavesand tidal action, provides movement of the docking and cleaning device110 and the boat 128 in relation to each other. This movement translatesinto frictional action of the scrubber 150 against the boat hull. Thefrictional action of scrubber 150 against the boat hull provides ascrubbing action to continuously clean the periphery of the boat hull atthe waterline—including the sides, bow, and stern—all while the boat 128is in the water.

When undocking the boat 128 from docking area 130, the latch 132A, 132Bis disengaged and the elongated members 120A, 120B are moved or swungapart, forming an opening between the second ends 124A, 124B of theelongated members 120A, 120B. The boat 128 then exits from docking area130 by moving the bow first between the opening formed by second ends124A, 124B. The scrubbers 150 on the elongated members 120A, 120B helpurge and guide the boat 128 out of the docking area 130 until the boat128 is clear of the device 110. Motors or other actuating devices knownto those skilled in the art so that the device is mechanically driven.Further, the motors may be adapted with receivers to respond to remotecontrol command signals

Third Exemplary Embodiment

Referring to FIGS. 6-7, a combination docking and cleaning device inaccordance with a third exemplary embodiment of the present invention isdesignated generally by the number 210. The device 210 of the thirdexemplary embodiment differs from the prior two embodiments in thatthere is no optional stationary base section. Thus, the device 210comprises a frame 212 having two elongated members 220A, 220B. Further,in this embodiment, the scrubber 250 is attached to the frame 212 usingan alternative bracket system. In addition, the device 210 of the thirdexemplary embodiment is comprised of a plurality of scrubber segmentshaving gaps between adjacent scrubber segments.

As shown in FIGS. 6-7, the boat docking and cleaning device 210 of thethird exemplary embodiment comprises a frame 212 shaped so that the bowof the boat 228 is docked first. Once the boat 228 is docked, the shapeof frame 212 generally conforms to the shape of the boat hull at thewaterline cross-section.

FIG. 6 illustrates the docking and cleaning device 210 in an “open”position with a boat 228 positioned therein. FIG. 7 illustrates thedocking and cleaning device in a “closed” position with the same boat228 positioned therein. The overall shape of frame 212 is substantiallyidentical to the frames 12, 112 described above with respect to theprior exemplary embodiments when the device is in the “closed” position.That is, the entire horizontal cross-section of the boat is surroundedby the frame 212 when in the closed position. Further, scrubbers 250 arepositioned along the entire interior periphery of the frame 212(although, as discussed above, there are gaps between adjacent scrubbersegments).

As shown in FIGS. 6-7, the docking frame 212 includes two elongatedmembers 220A, 220B having first ends 222A, 222B and second ends 224A,224B. The elongated members 220A, 220B are generally adapted to engagethe boat stern. In this embodiment, unlike in the first and secondembodiments discussed above, the first ends 222A, 222B are pivotablyattached together at movable joint 226, and not to a stationary basesection. The second ends 224A, 224B are adapted to move or swing towardand away from each other about a movable joint 226. This permits dockingof the boat 228 as generally illustrated in FIG. 6. As shown in FIG. 7,the second ends 224A, 224B are removably connected to each other to formthe enclosed docking area. Typical connection devices used to removablyconnect the second ends 224A, 224B of the elongated members 220A, 220Binclude, but are not limited to latches, clasps, hooks and eyes,buckles, ties, rope, locks, and the like.

In this embodiment, the elongated members 220A, 220B generally curvetoward each other so that their shapes correspond to the shape of thestern and bow of the boat 228 when the frame is in a “closed” position.As shown in FIGS. 6-7, elongated members 220A, 220B are generallyL-shaped.

FIG. 7A shows the cross-section of the frame 212. In this embodiment,one or more support brackets 244 are used to attach the scrubber 250 tothe frame 212. The brackets 244 are fixedly attached to frame 212 at oneend and are removably attached to the scrubber 250 at the other end.Thus, the scrubber 250 can be replaced as needed when the brushes 252become worn. The support brackets 244 include an elongated aperture orslot 246 to adjustably engage fasteners 248 such that the positionand/or angle of the scrubber 250 is adjustable. The angle of thescrubber is preferably 30 to 85 degrees relative to horizontal, and istypically about 60 to 80 degrees relative to horizontal (i.e. relativeto the waterline). Further, while the scrubber 50 in the first exemplaryembodiment extends along the entire interior periphery of the frame 12as one continuous scrubber unit, FIG. 7B illustrates a scrubber 250comprising a plurality of adjacently positioned scrubber segments250F-220I. In contrast to the second embodiment where the scrubbersegments 150A-150E form a continuous scrubber system, the scrubber 250in the third exemplary embodiment has a gap between some or all of theadjacently positioned scrubber segments 250F-250I to from anon-continuous scrubber 250.

Looking at FIGS. 6-7, frame 212 is typically held in position inrelation to dock 254 by mooring system 256. The mooring system 256 issimilar to the prior embodiments, i.e. one or more mooring lines 260connect the boat docking and cleaning device 210 to the dock 254 and/orpilings 258 at various attachment points 262.

The operation of the boat docking and cleaning device 210 is similar tothe prior embodiments. Looking to FIG. 6, the mooring lines 260 ofmooring system 256 are adapted to allow the frame 212 to be positionedin a desired location relative to the dock 254.

As shown in FIG. 6, for a docking operation, the frame 212 is in an“open” position. In the “open” position, the elongated members 220A,220B form a generally V-shape docking area 230. The second ends 224A,224B of the elongated members 220A, 220B provide an opening or entranceto docking area 230 through which a boat 228 may pass. As the bow of aboat 228 approaches and contacts device 210, the scrubbers 250 mountedto the elongated members 220A, 220B resiliently urge and guide the boat228 into the docking area 230. As the boat 228 advances, the scrubbers250 continue to urge and align the boat 228 into the docking area 230until the bow is adjacent first ends 222A, 222B. Once the bow of theboat 228 is adjacent first ends 222A, 222B, the elongated members 220A,220B are moved or swung toward each other until the second ends 224A,224B are in contact with one another or alternately connected together.The second ends 224A, 224B are moved towards each other, thereby placingthe device 210 in the “closed” position. The second ends 224A, 224B areheld together by engaging latches 232A, 232B.

As shown in FIG. 7, in the “closed” position, the frame 212 forms theenclosed docking area 230, holding the boat 228 in position. The boathull is continuously in contact with scrubber segments (e.g. 250F-250)forming the scrubber 250 on frame 212 of device 210. The motion of thewater causes frictional action to continuously clean the periphery ofthe boat hull at the waterline—including the sides, bow, and stern—allwhile the boat 228 is in the water. The boat 228 may be undocked byreversing the steps above in a manner similar to the prior embodiments.

Fourth Exemplary Embodiment

Referring to FIGS. 8-9, a combination docking and cleaning device inaccordance with a fourth exemplary embodiment of the present inventionis designated generally by the number 310. The device 310 comprises aframe 312 having two elongated members 320A, 320B. The device 310 issimilar to the device 210 of the third exemplary embodiment in that itdoes not comprise a base section. However, the device 310 of the fourthexemplary embodiment is different from that in the third embodimentinsofar as the frame 312 is shaped so that the stern of the boat 328 isdocked first. Once the boat 328 is docked, the shape of the frame 312generally conforms to the shape of the boat hull at the waterline.

FIG. 8 illustrates the docking and cleaning device 310 in an “open”position with a boat 328 positioned therein. FIG. 9 illustrates thedocking and cleaning device in a “closed” position with the same boat328 positioned therein. The overall shape of the frame 312 is the sameas in the prior exemplary embodiments when the device is in the “closed”position.

Similar to the third embodiment, the frame 312 of the fourth embodimentincludes two elongated members 320A, 320B having first ends 322A, 322Band second ends 324A, 324B. The elongated members 320A, 320B aregenerally adapted to engage the bow of the boat 328. This embodiment issimilar to the third embodiment in that the first ends 322A, 322B arepivotably attached together at movable joint 326, and not to astationary base section. The second ends 324A, 324B are adapted to moveor swing toward and away from each other about a movable joint 326. Thispermits docking of the boat 328 as generally illustrated in FIG. 9. Asshown in FIG. 9, the second ends 324A, 324B of the elongated members320A, 320B are removably connected to each other to form the encloseddocking area 330.

In this embodiment, the elongated members 320A, 320B generally curvetoward each other so that their shapes correspond to the shape of thehull of the boat 328 when the frame is in a “closed” position. As shownin FIGS. 8-9, elongated members 320A, 320B are generally L-shaped.

The cross-section of the device 310 and the scrubber configuration forthe fourth embodiment can be any of those described in FIGS. 3, 5A, 5B,7A, and/or 7B for the prior embodiments, or any combination thereof. Forexample, the cross-sectional construction or shape of the frame isnon-limiting. Further, the frame may be comprised of a buoyant ornon-buoyant material. In the latter case, the device may includeflotation devices such as buoys (not shown) attached to frame to allowframe to float. The frame may be positioned on or below the surface ofthe water. In addition, a scrubber or a plurality of scrubbers segmentsmay be provided along the frame. Preferably, the scrubbers, such asbrushes, extend along 50% to 100% (e.g., 50%, 60%, 70%, 80%, or 90%) ofthe periphery of the frame such that the brushes engage a majority ofthe horizontal cross-section of the boat hull, e.g., the waterlinesection or just below the waterline. The angle of the scrubbers may alsobe adjustable in relation to the shape of the boat hull or the positionof the device in the water.

Looking at FIGS. 8-9, the frame 312 is typically held in position inrelation to dock 354 by mooring system 356. The mooring system 356 issimilar to the prior embodiments. In general, one or more mooring lines360 connect the boat docking and cleaning device 310 to the dock 354and/or pilings 358 at various attachment points 362.

The operation of the boat docking and cleaning device is similar to thethird exemplary embodiment. Looking to FIG. 8, the mooring lines 360 ofmooring system 356 are adapted to allow the frame 312 to be positionedin a desired location relative to the dock 354.

As shown in FIG. 8, for a docking operation, the frame 312 is in an“open” position. In the “open” position, the elongated members 320A,320B form a generally U-shaped docking area 330. The second ends 324A,324B of the elongated members 320A, 320B provide an opening or entranceto the docking area 330 through which a boat 328 may pass. As the sternof a boat 328 approaches and contacts device 310, the scrubbers 350mounted to the elongated members 320A, 320B resiliently urge and guidethe boat 328 into the docking area 330. As the boat 328 advances, thescrubbers 350 continue to urge and align the boat 328 into the dockingarea 330 until the stern is adjacent to the first ends 322A, 322B. Oncethe stern of the boat 328 is adjacent to the first ends 322A, 322B, theelongated members 320A, 320B are moved or swung toward each other untilthe second ends 324A, 324B are in contact with one another or areotherwise connected together. Preferably, the second ends 324A, 324B areheld in contact with one another by the engaging latches 332A, 332B,thereby placing device 310 in the “closed” position. Other suitableconnection devices include hook and loop fasteners, ropes, clips, ties,and even velcro.

As shown in FIG. 9, in the “closed” position, the frame 312 forms theenclosed docking area 330, holding the boat 328 in position. The boathull is continuously in contact with the scrubber 350 on the frame 312of the device 310. The motion of the water causes frictional scrubberaction against the boat hull to continuously clean the periphery of theboat hull at the waterline—including the sides, bow, and stern—all whilethe boat 328 is in the water. To undock the boat, the elongated members320A, 320B are moved a part to the “open” position as generally shown inFIG. 8, and reversing the steps generally described above.

Fifth Exemplary Embodiment

Referring to FIGS. 10-11, a combination docking and cleaning device inaccordance with a fifth exemplary embodiment of the present invention isdesignated generally by the number 410. Similar to prior embodiments,the device 410 comprises a frame 412 having elongated members 420A, 420Bthat conform to the shape of the hull of a boat at a horizontalcross-section, preferably at the waterline cross-section. The device 410is similar to the prior embodiments, except that the elongated members420A, 420B are comprised of a plurality of frame sections 412A-412I.Although illustrated as having nine frame sections 412A-412I, it iswithin the scope of this invention for the quantity of frame sections tovary. e.g. the elongated members 420A, 420B may be comprised of 2, 3, 4,5, 6, 8, 9, 10, 11, 12, 13, 14, 15, etc., frame sections.

FIG. 10 illustrates the docking and cleaning device 410 in an “open”position with a boat 428 positioned therein. FIG. 11 illustrates thedocking and cleaning device in a “closed” position with the same boat428 positioned therein. As will be apparent, the overall shape of frame412 is similar to frames 12, 112, 212, 312 described above in priorembodiments when in the “closed” position. As shown in FIG. 10, the boatdocking and cleaning device 410 of the fourth exemplary embodimentcomprises a frame 412 shaped so that the bow of the boat 428 is dockedfirst. Once the boat 428 is docked, the shape of the frame 412 generallyconforms to the shape of boat hull at the waterline cross-section.

As shown in FIGS. 10-11, the docking frame 412 includes two elongatedmembers 420A, 420B having first ends 422A, 422B and second ends 424A,424B. The first elongated member 420A is comprised of fixedly connectedand adjustable frame sections 412A-D. The second elongated member 420Bis comprised of fixedly connected and adjustable frame sections 412E-I.The elongated member 420A and the elongated member 420B generally curvetoward each other so that their shapes correspond to the shape of thehull of the boat 428 when the frame 412 is in a “closed” position.

The frame sections may be fixedly connected using a number of connectingmeans, e.g. nails, screws, brackets, rivets, bolts, adhesive, Velcro,rope, and the like. Most preferably, however, the frame sections 412A-Hmay be adjusted to a number of fixed positions. In one aspect, as shownin FIGS. 12 and 13, frame sections 412A-D and 412E-H are fixedlyconnected together via adjustable connection brackets 470A, 470B. Eachframe section 412A-H comprises a first connection bracket 470A affixedto a first end of each frame section and a second connection bracket470B affixed to the second end of the frame section. The firstconnection bracket 470A is configured with a positioning through-hole472A and a guide through-hole 474A. The second connection bracket 470Bis configured with one positioning through-hole 472B.

The overall shape (i.e., the desired curve) of elongated members 420A,420B may be adjusted by altering the position of the frame sectionsrelative to one another. That is, the frame sections 412A-H may beadjusted to a number of fixed positions. More specifically, the shape ofthe elongated members 420A (comprising the frame sections 412A-D) and420B (comprising frame sections 412E-H) is adjusted by connecting thefirst connecting bracket 470A on a frame section with the secondconnecting bracket 470B of an adjacent frame section at an angle thatallows the frame sections to correspond generally to the shape of theboat hull at the waterline or other horizontal cross-section.

By way of example and not limitation, as shown in FIG. 13, frame section412A and 412B are placed in relation to each other such that connectionbracket 470A of the frame section 412A is positioned on top of or belowconnection bracket 470B of the frame section 412B. Once the positioningholes 472A, 472B are aligned, a fastener (e.g., screw, nail, bolt,etc.—not shown) is loosely inserted through the positioning holes 472A,472B. The frame sections are then positioned to correspond to the shapeof the boat hull at the waterline at a section, such that a desiredangle is formed between connection brackets 470A and 470B. The fastenerinserted in the positioning holes 472A, 472B is then tightened. Next, ahole (not shown), similar in diameter to the guide hole, is drilledthrough or otherwise formed in alignment with the guide hole 474A inconnection bracket 470A into the connection bracket 470B. Anotherfastener (not shown) is inserted through the guide hole 474A and thenewly drilled hole, and the fastener is tightened to hold the framesections at a fixed position (i.e., the desired angle). Alternatively, aseries of pre-drilled or pre-formed holes may be positioned inconnection bracket 470B and the fastener may be placed through any holethat aligns with the guide hole 474A to hold the frame at the desiredangle. By adjusting the angle between adjacent frame sections, theoverall curve or shape of the frame may be adjusted so that it bettercorresponds to the shape of the boat hull at a horizontal cross-section,such as the waterline section. This permits the user to customize theshape of the frame to a particular boat, if need be.

In this embodiment, as in the third embodiment discussed above, thefirst ends 422A, 422B are movably (preferably pivotably) attachedtogether at a movable joint 426. The second ends 424A, 424B are adaptedto move or swing toward and away from each other about the movable joint426. This permits docking of the boat 428 as generally illustrated inFIG. 10. As shown in FIG. 11, the frame section 412I of the elongatedmember 420B is further adapted to move or swing toward and away from theframe section 412A of the elongated member 420A about the movable joint480. The frame section 412I is removably connected to frame section 412Ato form the enclosed docking area as show in FIG. 11.

The cross-section of the device 410 for the fifth embodiment issubstantially the same as that described above in FIGS. 3, 5A, 5B, 7A,and/or 7B for the prior embodiments. For example, the cross-sectionalshape of the frame is non-limiting, and the frame may be comprised of abuoyant or non-buoyant material. In the latter case, the device mayinclude flotation devices such as buoys (not shown) attached to frame toallow frame to float. The frame may be positioned on or below thesurface of the water. In addition, a scrubber or a plurality ofscrubbers segments may be provided along the frame. Preferably, thescrubbers, such as brushes, extend along 50% to 100% of the periphery ofthe frame such that the brushes engage a majority of the horizontalcross-section of the boat hull, e.g., the waterline section or justbelow the waterline. The angle of the scrubbers may also be adjustablein relation to the shape of the boat hull or the position of the devicein the water.

Looking at FIGS. 10-11, the frame 412 is typically held in position inrelation to dock 454 by mooring system 456. The mooring system 456 issimilar to the prior embodiments. In general, one or more mooring lines460 connect the boat docking and cleaning device 410 to the dock 454and/or pilings 458 at various attachment points 462.

The operation of the boat docking and cleaning device is similar to theprior embodiments. Looking to FIG. 10, the mooring lines 460 of mooringsystem 456 are adapted to allow the frame 412 to be positioned in adesired location relative to the dock 454.

As shown in FIG. 10, for a docking operation, the frame 412 is in an“open” position. In the “open” position, the frame sections 412A-H forma generally V-shaped docking area 430. The opened end of the V-shapeddocking area provides an entrance to docking area 430 through which aboat 428 may pass. As the bow of the boat 428 approaches and contactsthe device 410, the scrubbers 450 mounted to frame sections 412A-Hresiliently urge and guide the boat 428 into the docking area 430. Asthe boat 428 advances, the scrubbers 450 continue to urge and align theboat 428 into the docking area 440 until the bow is adjacent to theframe sections 412D and 412E. Once the bow of the boat 428 contacts theframe sections 412D and 412E, the elongated members 420A, 420B are movedor swung toward each other and held in contact with the boat hull. Inaddition, the frame section 412I is moved toward frame section 412Aabout movable joint 480, thereby placing the device 410 in a “closedposition.” The second ends 424A, 424B of the elongated members 420A,420B are held in contact with one another by the engaging latches 432A,432B. Other suitable connection devices include hook and loop fasteners,ropes, clips, ties, and even velcro.

As shown in FIG. 11, in the “closed” position, the frame 412 forms theenclosed docking area 430, holding the boat 428 in position. The boathull is continuously in contact with scrubber 450 on the frame 412 ofthe device 410. The motion of the water causes frictional scrubbingaction to continuously clean the periphery of the boat hull at thewaterline—including the sides, bow, and stern—all while the boat 428 isin the water.

When undocking the boat 428 from docking area 430, the latches 432A,432B are disengaged and frame section 412I is moved to form an openingbetween the elongated member 420A, 420B. The boat 428 then exits fromdocking area 430 by moving the stern between the opening formed byelongated member 420A, 420B. The scrubbers 450 on frame sections 412A-Hhelp urge and guide the boat 428 out of the docking area 430 until theboat 428 is clear of the device 410.

Sixth Exemplary Embodiment

Referring to FIGS. 14 and 15, a combination docking and cleaning devicein accordance with a sixth exemplary embodiment of the present inventionis designated generally by the number 510. Like the second embodiment,the device 510 comprises a frame 512 having a base section 514 havingends 518A, 518B attached to two elongated members 520A, 520B. Like thefifth exemplary embodiment, the elongated member 520A conforms to theshape of the hull of a boat at the waterline and is comprised of aplurality of frame sections 512A-D, and the elongated member 520Bconforms to the shape of the hull of a boat at the waterline and iscomprised of a plurality of frame sections 512E-H. Although the device510 is illustrated as having eight frame sections 512A-512H, it iswithin the scope of this invention for the quantity of frame sections tovary. The frame sections may be the same or different in size, shape,and overall construction.

The device 410 of the fifth exemplary embodiment is designed as“bow-first,” while the device 510 of the sixth exemplary embodiment isdesigned as “stern-first” when docking. FIG. 14 illustrates the dockingand cleaning device 510 in an “open” position with a boat 528 positionedtherein. FIG. 15 illustrates the docking and cleaning device in a“closed” position with the same boat 528 positioned therein. A shown inboth FIGS. 14 and 15, the base section 514 is generally shaped tocorrespond to the stern of the boat 528. The overall shape of the frame512 is shaped so that once the boat 528 is docked, the shape of theframe 512 generally conforms to the shape of boat hull at the waterline.

As shown in FIGS. 14 and 15, the frame 512 includes two elongatedmembers 520A, 520B having first ends 522A, 522B and second ends 524A,524B. The first elongated member 520A is comprised of fixedly butadjustably connected frame sections 512A-D. The second elongated member520B is comprised of fixedly but adjustably connected frame sections512E-H. The elongated member 520A and the elongated member 520Bgenerally curve toward each other so that their shapes correspond to theshape of the hull of the boat 528 when the frame is in a “closed”position.

The methods for connecting the frame sections in device 510 of the sixthembodiment is substantially the same as that described above for thefifth embodiment. It is preferably that each of the frame sections512A-D and 512E-H are held in a substantially fixed position. It will beapparent that there may be some play or give at the connections,however, when for example, rope is used to tie the frame sectionstogether.

In this embodiment, as in the second embodiment discussed above, thefirst ends 522A, 522B of elongated members 520A, 520B are movablyattached (preferably pivotably attached) to ends 518A, 518B of the basesection 514 respectively at movable joints 526A, 526B. The second ends524A, 524B of elongated members 520A, 520B are adapted to move or swingtoward and away from each other about movable joints 526A, 526B. Thispermits docking of the boat 528 as generally illustrated in FIGS. 14 and15. As shown in FIG. 15, the second ends 524A, 524B are removablyconnected to each other to form the enclosed docking area 530.

The cross-section of the device 510 for the sixth embodiment issubstantially the same as that described above in FIGS. 3, 5A, 5B, 7A,and/or 7B for the prior embodiments. For example, the cross-sectionalshape of the frame is non-limiting, and the frame may be comprised of abuoyant or non-buoyant material. In the latter case, the device mayinclude flotation devices such as buoys (not shown) attached to frame toallow frame to float. The frame may be positioned on or below thesurface of the water. In addition, a scrubber or a plurality ofscrubbers segments may be provided along the frame. Preferably, thescrubbers, such as brushes, extend along 50% to 100% of the periphery ofthe frame such that the brushes engage a majority of the horizontalcross-section of the boat hull. e.g. the waterline section or just belowthe waterline. The angle of the scrubbers may also be adjustable inrelation to the shape of the boat hull or the position of the device inthe water.

Looking at FIGS. 14 and 15, the frame 512 is typically held in positionin relation to the dock 554 by a mooring system 556. The mooring system556 comprises one or more mooring lines 560 to connect the device 510 tothe dock 554 and/or pilings 558 at various attachment points 562.

The operation of the boat docking and cleaning device is similar to theprior embodiments. Looking to FIG. 14, the mooring lines 560 of themooring system 556 are adapted to allow the frame 512 to be positionedin a desired location relative to the dock 554.

As shown in FIG. 14, for a docking operation, frame 512 is in an “open”position. In the “open” position, the frame 512 forms a generallyU-shaped docking area 530. The opened end of the U-shaped docking areaprovides an entrance to the docking area 530 through which the boat 528may pass. As the stern of a boat 528 approaches and contacts the device510, scrubbers 550 mounted on elongated members 520A, 520B resilientlyurge and guide the boat 528 into the docking area 530. As the boat 528advances, the scrubbers 550 continue to urge and align the boat 528 intothe docking area 540 until the stern of boat 528 contacts the basesection 514. Once the stern of the boat 528 contacts base section 514,elongated members 520A, 520B are moved or swung toward each other andheld in contact with the boat hull by engaging latches 532A, 532B,placing device 510 in the “closed” position.

As shown in FIG. 15, in the “closed” position, frame 512 forms encloseddocking area 530, holding the boat 528 in position. The boat hull iscontinuously in contact with scrubber 550 on frame 512 of device 510.The motion of the water causes a frictional scrubbing action tocontinuously clean the periphery of the boat hull at thewaterline—including the sides, bow, and stern—all while the boat 528 isin the water.

When undocking the boat 528 from docking area 530, latches 532A, 532Bare disengaged and elongated members 520A, 520B are moved to form anopening between elongated members 520A, 520B. The boat 528 then exitsfrom docking area 530 by moving the bow between the opening formed byelongated members 520A, 520B. The scrubbers 550 on elongated members520A, 520B help urge and guide the boat 528 out of the docking area 530until the boat 528 is clear of the device 510.

Seventh Embodiment

Referring to FIG. 16, a combination docking and cleaning device inaccordance with a seventh exemplary embodiment of the present inventionis designated generally by the number 610. The device is generally shownin a “closed” position with a boat 628 positioned therein. The device610 of the seventh exemplary embodiment differs from the priorembodiments in that there is a line or rope 621 attached to each end ofto the base section 614 that holds the boat in contact with the basesection 614. Thus, the frame 612 of the docking and cleaning device 610contacts the boat at about 50% to 60% of the periphery of the boat hullat the waterline when the device is in the “closed” position.

More specifically, the device 610 comprises a frame 612 and the line orrope 621. The frame 612 comprises a base section 614 which is generallyV-shaped and comprises first and second members 614A, 614B, whichconverge and join at apex 616 at one end and extend and bow outwardlyfrom apex 616 to ends 618A, 618B. It will be appreciated that the firstand second members 614A, 614B of the base section 614 may be fixedly ormovably connected (e.g., pivotably connected) at apex 616.

The cross-section of the device 610 for the sixth embodiment can beconstructed as set forth in any one of the prior embodiments, e.g., inFIGS. 3, 5A, 5B, 7A, and/or 7B. Further, the frame may be constructed ofone or more frame sections, and the scrubbers may be comprised of one ormore scrubber segments. The frame may also be constructed of one or moreelongated members attached to optional base section as discussed above.

Looking at FIG. 16, the frame 612 is typically held in position inrelation to dock 654 by mooring system 656. The mooring system 656 issimilar to the prior embodiments, i.e., one or more mooring lines 660connect the boat docking and cleaning device 610 to the dock 654 and/orpilings 658 at various attachment points.

The operation of the boat docking and cleaning device 610 is similar tothe prior embodiments. For a docking operation, the boat docking andcleaning device 610 is placed in the “open” position where line 621 isremoved from the one end 618A, 618B of the base section 614 to providean opening or entrance to docking area 630 through which a boat 628 maypass. As the bow of a boat 628 approaches and contacts device 610, thescrubbers 650 resiliently urge and guide the boat 628 into the dockingarea 630. As the boat 628 advances, the scrubbers 650 continue to urgeand align the boat 628 into the docking area 630 until the bow isadjacent apex 616. Once the bow of the boat 628 is adjacent apex 616,the line or rope 621 is moved around the stern of the boat 628 andreaffixed to base section 614 at the end 618B.

As shown in FIG. 16, in the “closed” position, the frame 612 togetherwith the rope or line 621 forms the enclosed docking area 630, holdingthe boat 628 in position. The boat hull is continuously in contact withscrubber 650 on frame 612 of device 610. The motion of the water causesfrictional action to continuously clean about 50 to 60% of the peripheryof the boat hull at the waterline—all while the boat 628 is in thewater. The boat 628 may be undocked by reversing the steps above.

It will be appreciated that although the seventh embodiment illustratesboat docking a cleaning device having a frame which is adapted toreceive the bow of the boat first, similar devices which receive thestern first are within the scope of the present invention. In suchembodiments, the frame may be a single unitary member shaped tocorrespond to the stern of the boat or alternatively the frame may becomprised of movable elongated members, such as that illustrated inFIGS. 4 and 5, although truncated in length and attached together usinga rope. Such devices would still be capable of cleaning a substantialportion of the boat hull at the a horizontal cross section (e.g., awater line cross section), although in general devices having scrubberswhich engage close to 100% of boat hull at the water line are mostpreferred.

From the foregoing, it will be seen that this invention is one welladapted to attain all ends and objectives hereinabove set forth,together with the other advantages which are obvious and which areinherent to the invention.
